Wife of 7 months (together 8.5 years) and I do not want children, so we're childfree as well. At 25, we're still not quite ready to make me sterile, as we still make the occasional "if we have kids..." statement. There were a lot of those made while we were dating, but she's an aunt to 13, 2 of which she spent the first couple months with (temporarily lived with her sister), making her hesitant to have kids of her own, and babies scare me with their seemingly random screaming and endless poop streams. Some part of me still feels like I won't be complete / live a full life if we don't have kids, but perhaps that will change; it's the romantic idea of having children, while my rational side keeps telling me it's a bad idea.
